Acids & Bases Flashcards
Acid in terms of Brønsted-Lowry model
A proton donor.
Base in terms of Brønsted-Lowry model
A proton acceptor.
Ionisation
The reaction of a molecular substance with water to produce ions.
Strong Acid
An acid that ionises almost completely in an aqueous solution.
Weak Acid
An acid that ionises partially in an aqueous solution.
Dissociation
The splitting of an ionic compound into its ions.
Strong Base
A base that ionises completely in an aqueous solution.
Weak Base
A base that dissociation/ionises partially in an aqueous solution.
Amphoteric (or Amphiprotic) substance
A substance that can act as either an acid or a base.
Salt
A substance in which the hydrogen of an acid has been replaced by a cation.
Hydrolysis of a salt
A reaction of an ion (from a salt) with water.
Neutralisation (or the equivalence point)
The pint where an acid and base have reacted so neither is in excess.
Neutralisation (or the equivalence point)
A chemical reaction in which an acid and a base react so that neither is in excess.
Standard Solution
A solution of known concentration.
List examples of strong acids
